Variable Rate Series A Perpetual Preferred Stock

This supplement relates to the offer and sale of shares of our Variable Rate Series A Perpetual Preferred Stock, par value $0.001 per share (the "SATA Stock"), pursuant to the Amended and Restated Controlled Equity Offering^SM Sales Agreement, dated as of June 5, 2026, as amended, supplemented or otherwise modified from time to time (the "Sales Agreement"), by and among us and the sales agents identified therein (the "Agents") and supplements Amendment No. 1 dated June 5, 2026 to the base prospectus supplement dated December 9, 2025 related thereto. This supplement should be read in conjunction with the base prospectus supplement, as amended, and the accompanying prospectus dated September 15, 2025. Except as set forth herein, the base prospectus supplement, as amended, and the accompanying prospectus remain unchanged.

We are filing this supplement to reflect the termination of the Sales Agreement by The Benchmark Company, LLC ("Benchmark") solely with respect to its rights and obligations thereunder, and to amend the disclosure under the section heading "Plan of Distribution" in the base prospectus supplement, as amended, as set forth below.

Amendment to Plan of Distribution:

On November 6, 2026, in connection with the completion of the acquisition of Benchmark by StoneX Group Inc., we and Benchmark entered into a termination agreement pursuant to Section 13(c) of the Sales Agreement, terminating the Sales Agreement solely with respect to Benchmark's rights and obligations thereunder, effective November 16, 2026. Such termination does not affect the rights and obligations of the other Agents under the Sales Agreement, including StoneX Financial Inc., an affiliate of Benchmark, which remains an Agent under the Sales Agreement. Accordingly, effective as of November 16, 2026, Benchmark is no longer an Agent under the Sales Agreement, and each reference to the term "Agent" or "Agents" in the base prospectus supplement, as amended, is hereby amended to exclude Benchmark and its broker-dealer affiliates.

Investing in our SATA Stock involves a high degree of risk. You should review carefully the risks and uncertainties referenced under the heading "Risk Factors" on page S-12 of the base prospectus supplement dated December 9, 2025 and page 7 of the accompanying prospectus, in the other documents that are incorporated by reference into the base prospectus supplement, as amended and any free writing prospectuses.

Neither the Securities and Exchange Commission nor any state or foreign securities commission or regulatory authority has approved or disapproved of these securities or passed upon the adequacy or accuracy of this supplement, the base prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.
